The passport is designed to be super thin and flexible. A page of the OLED passport measures 300µm thick which, when integrated with color display, is still just 700µm. A contactless reader provides power for the passport, eliminating the need to equip it directly with batteries.

Being an AMOLED display though, it's guaranteed to consume low amounts of power. That added with the fact that it'd obliterate the need for paper for making passports make the technology promising.

Unfortunately, I can't help but think that electronic passports could be dangerous. What if a hacker gets their hands on it? According to Samsung though, it's extremely secure, plus it could be laminated as it's heat-resistant, preventing the possibility of tampering. Additionally, aside from authorized personnel no one can easily alter its contents. The OLED passport would be able to provide data that current passports cannot, including moving pictures of the owner.

Don't hold your breath for it though--no one knows if and when the technology would actually be used in the future.
